It's great. it handle some bad input URLs and make urlsplit more robust. |
xiaoge1001 commentedMar 8, 2023
This PR moves us in the direction I'd like to see the APIs go. I'm not sure it could ever be backported as a security fix for the long list of analysis reasons I just posted over in the Issue, but it might make sense in 3.12. I believe there's still an open question of trailing spaces on paths potentially carrying meaning in some (presumably not-HTTP) scenarios (see the Issue analysis). So stripping all of the C0 characters early on might not be the right approach. But they should be stripped from most places. Lets keep this PR around as a likely option. (I'll still put a do-not-submit tag on it for now, just as an indicator that we're not ready to accept ityet). |

Is it planned to merge the current patch to python3.12? I don't find there's been any discussion recently. |
Many existing applications rely (for better or worse) on the trailing spacesbeing preserved by this API. So this moves more conservative and keeps those.The issue this change is addressing is triggered by leading spaces.One example library relyong on behavior: Django's URL validator library (atleast in Django 3.2 and earlier; I have not checked later versions). Iftrailing spaces are stripped, its logic that involves urllib.parse for one logicpath within its checks can fail to reject some URLs as invalid.
Also be explicit about specifying utf-8 on encode and decode.
Results from internal testing across a huge body of code (including test suites of many open source libraries and applications): Stripping the C0 characters from the left hand side doesn't appear to cause any problems. Stripping them from the right hand side of the URL does, as existing code calling urllib.parse such as i've updated the PR to use lstrip on the url. |
I'm a lot more confident that we could actually backport this as a security bug fix without breaking the world now. As for documentation to be added to warn users of these APIs, I'm not quite sure how to word that and what to convey yet. I've opened up as a discussion inhttps://discuss.python.org/t/how-to-word-a-warning-about-security-uses-in-urllib-parse-docs/26399. |

The first beta is expected to be released on Monday and it'd be very nice to have this in the release.

remove "trailing"
I intend to get this in before the next releases are cut. The last bit is for me to add some appropriate text to the urllib.parse documentation recommending that people verify that the outputs from the API makes sense before trusting any of them. |
We have one week to the first beta. Is there anything I can help you with? |
The added section describing the situation is longer than I might want,but being more brief just leaves open questions.This is a lighter worded version of my original text proposed inhttps://discuss.python.org/t/how-to-word-a-warning-about-security-uses-in-urllib-parse-docs/26399
